［第１実施形態］
図１は、本発明の一実施形態に係る配線基板５を備えるステータ１を示す斜視図である。図２は、本実施形態のステータ１の分解斜視図である。
図１及び図２に示すステータ１は、電動機１００を構成するものである。 [First Embodiment]
FIG. 1 is a perspective view showing a stator 1 including a wiring board 5 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the stator 1 of the present embodiment.
A stator 1 shown in FIGS. 1 and 2 constitutes an electric motor 100.

本実施形態のステータ１は、ステータコア３と、コイル（巻線）４と、配線基板５と、動力線コネクタ（コネクタ）６と、を含んで構成される。   The stator 1 of this embodiment includes a stator core 3, a coil (winding) 4, a wiring board 5, and a power line connector (connector) 6.

ステータコア３は、電動機１００の中心部に円形状の孔部を有する複数枚の鋼板が積層されて構成される。本実施形態のステータコア３は、孔部の周囲に径方向の外側に突出する複数のティース部３１を備える。複数のティース部３１は、周方向で等間隔に配置されており、隣り合うティース部３１の間には、上下方向に連通するスロット３２が形成される。ステータコア３の各ティース部３１には、コイル４が形成される。   The stator core 3 is configured by laminating a plurality of steel plates having circular holes at the center of the electric motor 100. The stator core 3 of the present embodiment includes a plurality of teeth portions 31 that protrude outward in the radial direction around the hole portion. The plurality of tooth portions 31 are arranged at equal intervals in the circumferential direction, and slots 32 communicating in the vertical direction are formed between adjacent tooth portions 31. A coil 4 is formed on each tooth portion 31 of the stator core 3.

ステータコア３の円形状の孔部の内側には不図示のロータが回転自在に配置される。ステータコア３の上方には、配線基板５及び動力線コネクタ６が配置され、動力線コネクタ６よりコイル４に電力が供給されることで、このロータが回転する。   A rotor (not shown) is rotatably disposed inside the circular hole of the stator core 3. A wiring board 5 and a power line connector 6 are disposed above the stator core 3, and when the power is supplied from the power line connector 6 to the coil 4, the rotor rotates.

コイル４は、ステータコア３のスロット３２を通して、各ティース部３１に導線が所定回数巻き回されることにより形成される。コイル４の一側の端部４１は、ステータコア３の上方に向かって延びるように配置される。また、コイル４の他側の端部（不図示）は、ステータコア３の下方において、円周上所定の間隔をおいて配置される別のコイル４の他側の端部に結線される。これにより、複数のコイル４のうち所定のコイル４同士の間で通電が行われる。
また、巻き回されたコイル４の端部４１以外は、絶縁体が被覆された状態となっている。 The coil 4 is formed by winding a conductive wire around each tooth portion 31 through a slot 32 of the stator core 3 a predetermined number of times. The end 41 on one side of the coil 4 is arranged to extend upward from the stator core 3. The other end (not shown) of the coil 4 is connected to the other end of another coil 4 arranged at a predetermined interval on the circumference below the stator core 3. Thereby, electricity supply is performed between predetermined coils 4 among the plurality of coils 4.
Moreover, it is in the state where the insulator was coat | covered except the edge part 41 of the coil 4 wound.

配線基板５は、その中心に円形の貫通孔が形成されるリング状に構成される。配線基板５は、各端部４１に圧着結線することにより、各端部４１に電力を供給するように接続される。   The wiring board 5 is configured in a ring shape in which a circular through hole is formed at the center. The wiring board 5 is connected so as to supply power to each end 41 by being crimped to each end 41.

本実施形態の配線基板５は、回路基板７と、該回路基板７に配置される圧着端子７１と、を含んで構成される。また、回路基板７（配線基板５）の外周側には、動力線コネクタ６が取り付けられる。   The wiring board 5 of this embodiment includes a circuit board 7 and a crimp terminal 71 disposed on the circuit board 7. A power line connector 6 is attached to the outer peripheral side of the circuit board 7 (wiring board 5).

回路基板７は、その中心に円形の貫通孔が形成され、リング状に構成される。回路基板７には、端部４１に対応した数の圧着端子７１が配置される。本実施形態では、回路基板７の内周側及び外周側のそれぞれに円周方向で等間隔に配置される。   The circuit board 7 is formed in a ring shape with a circular through hole formed at the center thereof. A number of crimp terminals 71 corresponding to the end portions 41 are arranged on the circuit board 7. In the present embodiment, the circuit boards 7 are arranged at equal intervals in the circumferential direction on the inner peripheral side and the outer peripheral side, respectively.

また、回路基板７の上面には、圧着端子７１に対応する位置に放射状に延びる溝部７３が形成される。溝部７３は、上下方向に所定の深さを有し、周方向で等間隔に形成される。回路基板７の溝部７３は、その大きさが圧着部７２に被覆（圧着）された状態の端部４１を圧着端子７１と共に収容可能に構成される。
回路基板７は、上面に沿って端部４１を溝部７３の内側に収容することにより、端部４１同士の接触を防ぎ、端部４１同士の接触を原因とする接触不良を防ぐことができる。また、回路基板７は、端部４１同士の短絡を防ぐことができることから、端部４１の絶縁処理等が不要となり、配線工程に係る作業数を削減することができる。そのため、回路基板７は、配線工程を単純なものにできる。 In addition, on the upper surface of the circuit board 7, grooves 73 that extend radially are formed at positions corresponding to the crimp terminals 71. The groove portions 73 have a predetermined depth in the vertical direction and are formed at equal intervals in the circumferential direction. The groove portion 73 of the circuit board 7 is configured to be able to accommodate the end portion 41 in a state where the size is covered (crimped) by the crimp portion 72 together with the crimp terminal 71.
The circuit board 7 accommodates the end portion 41 inside the groove portion 73 along the upper surface, thereby preventing contact between the end portions 41 and preventing contact failure caused by contact between the end portions 41. In addition, since the circuit board 7 can prevent the end portions 41 from being short-circuited, an insulation process or the like of the end portions 41 is not necessary, and the number of operations related to the wiring process can be reduced. Therefore, the circuit board 7 can simplify the wiring process.

圧着端子７１は、周方向において溝部７３の内周側と外周側に交互に設けられる。即ち、内周側の圧着端子７１と外周側の圧着端子７１は、径方向で重ならないように配置される。圧着端子７１は、圧着を行う前の状態では上方に向かって延びるように配置される。圧着端子７１は、回路基板７の端面に沿って延びる端部４１を圧着し、圧着した端部４１を回路基板７の面に沿った状態に曲げ可能に構成される。   The crimp terminals 71 are alternately provided on the inner peripheral side and the outer peripheral side of the groove 73 in the circumferential direction. That is, the inner peripheral crimp terminal 71 and the outer peripheral crimp terminal 71 are arranged so as not to overlap in the radial direction. The crimp terminal 71 is disposed so as to extend upward in a state before crimping. The crimp terminal 71 is configured to crimp an end portion 41 extending along the end surface of the circuit board 7 and bend the crimped end portion 41 in a state along the surface of the circuit substrate 7.

本実施形態の圧着端子７１は、コイル４の端部４１に圧着される圧着部７２と、圧着部７２を回路基板７の本体部分に接続する接続部７４と、を備える。   The crimp terminal 71 of this embodiment includes a crimp part 72 that is crimped to the end 41 of the coil 4 and a connection part 74 that connects the crimp part 72 to the main body portion of the circuit board 7.

圧着部７２は、半円筒状に形成される。圧着部７２は、端部４１の側周部を覆うようにして端部４１に圧着されてコイル４と回路基板７が結線される。圧着部７２は、コイル４の端部を覆う状態で圧着されるので、接触不良を起こすことなく端部４１と圧着端子７１の接続が良好に維持される。   The crimping part 72 is formed in a semi-cylindrical shape. The crimp portion 72 is crimped to the end portion 41 so as to cover the side peripheral portion of the end portion 41, and the coil 4 and the circuit board 7 are connected. Since the crimping part 72 is crimped in a state of covering the end part of the coil 4, the connection between the end part 41 and the crimping terminal 71 is favorably maintained without causing contact failure.

接続部７４は、圧着を行う前の状態では圧着部７２の下方に位置しており、回路基板７の平面部分側に折り曲げ可能に構成される。なお、内周側の圧着端子７１は外周側に折り曲げられ、外周側の圧着端子７１は内周側に折り曲げられることで、溝部７３に収容される。   The connecting portion 74 is positioned below the crimping portion 72 before being crimped, and is configured to be bendable on the plane portion side of the circuit board 7. The inner peripheral side crimp terminal 71 is bent toward the outer peripheral side, and the outer peripheral side crimp terminal 71 is bent toward the inner peripheral side to be accommodated in the groove 73.

動力線コネクタ（コネクタ）６は、回路基板７の上面側に配置される。本実施形態の動力線コネクタ６の外側面には、動力線を接続するための３つの入力部６１と、アースと接続するためのアース部６２が設けられる。また、動力線コネクタ６の内側面には、導線６３が備えられ、該導線６３は、各端子８１に電気的に接続される。３つの入力部６１には、それぞれ三相電源交流装置からの交流電流を供給する動力線が接続される。   The power line connector (connector) 6 is disposed on the upper surface side of the circuit board 7. On the outer surface of the power line connector 6 of the present embodiment, three input parts 61 for connecting power lines and a ground part 62 for connecting to the ground are provided. In addition, a conductive wire 63 is provided on the inner surface of the power line connector 6, and the conductive wire 63 is electrically connected to each terminal 81. Power lines for supplying an alternating current from a three-phase power supply AC device are connected to the three input units 61, respectively.

以上の各構成を備えるステータ１の製造工程について、図３及び図４を参照して以下に説明する。図３及び図４は、本実施形態に係る配線基板５の設置動作を説明するための図である。
先ず、図３に示すように、コイル４を巻き回した状態のステータコア３の上方から、端部４１が接続部５４に当接するようにして、配線基板５を設置する。これにより、端部４１は、半円筒状の圧着部７２の内側に配置される。 A manufacturing process of the stator 1 having the above-described configurations will be described below with reference to FIGS. 3 and 4. 3 and 4 are views for explaining the installation operation of the wiring board 5 according to the present embodiment.
First, as shown in FIG. 3, the wiring board 5 is installed from above the stator core 3 in a state where the coil 4 is wound so that the end portion 41 comes into contact with the connection portion 54. As a result, the end portion 41 is arranged inside the semi-cylindrical crimping portion 72.

続いて、図４に示すように、圧着部７２の開口部分を閉じることにより、圧着部７２で端部４１の側周部を覆う。その後、これにより、圧着部７２は端部４１に結線し、動力線コネクタ６による電力の供給が可能な状態になる。   Subsequently, as shown in FIG. 4, the side periphery of the end portion 41 is covered with the crimping portion 72 by closing the opening of the crimping portion 72. Thereafter, as a result, the crimping portion 72 is connected to the end portion 41, and the power line connector 6 can supply power.

その後、圧着端子７１が圧着された状態の端部４１を折り曲げて、溝部５３に収容する。これにより、図１に示すように、配線基板５は、端子５１をすべての端部４１に圧着すると共に、端部４１を溝部５３に整線する。   Thereafter, the end 41 in a state where the crimp terminal 71 is crimped is bent and accommodated in the groove 53. Thereby, as shown in FIG. 1, the wiring board 5 crimps the terminals 51 to all the end portions 41 and straightens the end portions 41 to the groove portions 53.

そして、このステータ１の内側に、不図示のロータを配置することで、電動機１００が製造される。   And the electric motor 100 is manufactured by arrange | positioning the rotor not shown inside this stator 1. FIG.

(1) According to the electric motor 100 including the wiring board 5 of the present embodiment, the wiring board 5 is attached to the stator 1 around which the plurality of coils 4 are wound, and the circuit board 7 attached to the stator 1 and the circuit board 7 and a plurality of crimp terminals 71 that can be crimped to the end portion 41 of the coil 4.

このような、配線基板５では、先ず各コイル４の端部４１は、回路基板７の圧着端子７１の圧着部７２に覆うように圧着されることで、端部４１は圧着端子７１に結線される。
これにより、本実施形態の配線基板５によれば、コイル４への配線は、ステータコア３上への回路基板７の設置作業と、端部４１と圧着端子７１との圧着作業のみによって行われる。その結果、従来のように手間のかかるはんだ付け作業は不要となると共に、コイル４は圧着端子７１に確実に結線され、配線に係る作業は単純化でき、作業時間を効果的に短縮できる。
また、本実施形態の構成によれば、端部４１は圧着端子７１と共に、回路基板７の面に沿った状態に曲げられる。その結果、接触不良の起きにくい電動機１００の配線基板５を提供することができる。そして、従来の構成のような被覆除去を省略することもでき、より好適に配線作業を行うことができる。 In such a wiring board 5, first, the end 41 of each coil 4 is crimped so as to cover the crimping part 72 of the crimping terminal 71 of the circuit board 7, so that the end 41 is connected to the crimping terminal 71. The
Thereby, according to the wiring board 5 of this embodiment, the wiring to the coil 4 is performed only by the installation work of the circuit board 7 on the stator core 3 and the crimping work of the end portion 41 and the crimp terminal 71. As a result, time-consuming soldering work as in the prior art becomes unnecessary, and the coil 4 is securely connected to the crimp terminal 71, the work related to wiring can be simplified, and the working time can be effectively shortened.
Further, according to the configuration of the present embodiment, the end portion 41 is bent together with the crimp terminal 71 in a state along the surface of the circuit board 7. As a result, it is possible to provide the wiring board 5 of the electric motor 100 that is unlikely to cause poor contact. And removal of a coating | cover like the conventional structure can also be abbreviate | omitted and a wiring operation | work can be performed more suitably.
